MAISH, OF FRAMINGHAM, 'MASSACHC'SETTS, ASSIGNOR TO DENNISON MANU- FACTURING COMPANY, OF MASSACHUSETTS INDEX TAB AND Mnirnon Application filed. August 23, 1928. Serial ,I No.- 301,641.

This invention relates to index tabs for use on guide cards, filing containers, record books, etc., having for its principalobjects the provision of'a tab which is simpleand economical in construction, which holds a writing surface permanently against misplacement and loss and against wear and soil and at the same time so that it is accessible for writing either by hand or on a typeing or experience, which is accurately positioned on a guide card by virtue of its structural characteristics. and which is generally superior to index tabs of the class to which it relates.

The generic features of the invention are illustrated by the concrete embodiment shown in the accompanying drawings in which:

Fig. 1 is a face view of the inside of a tab prlaifore' application to a guide card or the Fig.2 is a section on line 22 of Fig. 1;

Fig. 3 is a side view of the tab applied to a guide card or other sheet of material;

Bdig. 4 is a section on line H of Fig. 3; an

Fig. 5 is an end view of a tab ready to be applied toa card. I

The particular embodiment of the inven tion chosen for the purpose of illustration comprises a band 1 of paper or other writing material fast to the face of a strip 2 of 1 cellophane or other flexible transparent material which is folded over the upper edge of the band '1 with both legs extending beyond the lower edge'of the band for attachment to the sheet 3 which maybe a guide card, page of a book, or other sheet of material. The band 1 and sheet3 are-preferably cemented to the strip 2 inwhich case the ce-- ment is preferably appliedto the strip 2 in the form of a gum, either hard-drying or plastic, the band 1 then being applied to the strip and the strip subsequently being applied to the guide card as shown in Figs. 3 and 4, the shoulder formed by the lower edge of the band 1 engaging the upper edgeof the guide card to position'the tab before the adhesive margins of the strip are pressed against the card 3. Thus in the case of a series of tabs afiixed to a group of cards in a filing cabinet or tray. the tabs will project above'th e cards equidistantly, and therefore not'only present a neat appearance but also facilitate the inspection'of successive tabs.

The strip may begummed only throughout the areas engaged by the band and card but the process of making the tab is simplified by gumming the strip throughout one side in which case the strip may or may not be stuck to the front face of the band. By

same amount if the-front portion of the strip be'drawn down snugly over the upper edge of the band beforeit is pressed against the front'of the card. 7 l V These index tabs may be delivered to the user in the fiat form shown in Figs. 1 and 2 or in folded form more or less as shown in Fig. 5. In the latter case the tabs are unfolded for writing the desired indicia on the bands of writing material. In either case the tabs may readily be inserted in a typewriter; indeed the narrow bands may be typed with much greater facility when mounted on the wider strips.

When using cellophane, the preferred material for the strips, the gum may be caused to adhere by first coating the cellophane with a priming coat comprising 45 parts animal glue, parts Water and 5 parts acetic acid.

I claim:

1. An index tab comprising a strip of flexible material gummed on one side and foldable into the shape of a U with its front and rear legs lying in closely spaced relationship and with the gummed surface inside, and a band of writing material held by the gum on the rear leg near the fold line, the front leg having a portion through which said band is visible and the margins of both legs extending beyond said band when the strip is folded so that the legs may be held by the gum to the opposite sides of a guide card or the like.

2. An index tab eolnprisinga strip of flexible transparent material folded over a band of writing material with the fold line near one edge of the band, the strip having gummed portions on opposite sides of the fold line beyond the other edgeof the band for attaehment'to the opposite sides ofa sheet of paper or .thelike and the band adheringto the stripon one side. i 7

10V '3. An indextab comprising a'strip'of flexible materialgnmmed on one side-and fold-- able into the shape of a U with its front and rear legs lying in closely spaced relationship and with the gummed surface inside, and a I band of writing material held by the 'gurn onv the rear leg near the fold line, the front leg having a portion through whichsaid band is Visible and the margins of both legseX- tending beyond said band when the strip is 7. folded so'that the legs may beheld by the gum to the opposite sides of a sheet of paper or the like, said band having sufiieient thickness to afford a shoulder .for engagement With the edge of said sheet to positi-on'the tab A in predeterminedrelation preparatory to attaching said legs'as aforesaid.

V 4. The-method of labeling a guide card or the like'whichcomprises gumming a strip of flexible transparent material on one side,

sticking anarrow band of writingmaterial on the gummed strip'near its central region, typing the-band,- folding, the strip over the band, and then sticking the gummed margins 'of the strip to opposite sides of said card with 3 said band visible beyond the edgepof the'sheet.
